To all whom it may concern:

Be it known that 1, Heroes: Vmom-er,

of Ridgewood, in the county of Ber en and State oi New Jersey, have inven'te a 6 tam new and. useful lmpro'venisit in Loco "'be of comparatively simple and inexpenmotive-Feed-lVater Heaters, c which 71in provement the following is a speciiiozzt My invention relates to locomotive Water-heaters of the surface type, in w ca the transierence of heat from seating agent, which may be either exhaust SJQEIU or Waste gases, to the feed Water. is effected through separating walls of metal Either one or the other of the heating mediams noted has, heretofore, been ordinarily applied, and apparatus operating under their joint and serial application has also been put in practice to a limitul extent A. substantial objection to the use of exhaust steam only, is, that if taken in sufficient quantity to raise the temperatme of water to such degree as Will effect an stantial economy, the action of the exhai: jet upon the fire is subject to be so fee diminished as to impair the steaming qualities of the locomotive. Feed Water heaters desigi'iedto utilize the Waste have, in most, if not in all cases, been located in the smoke box, with the results oi ohjectionably obstructing it, and of being rapidly deteriorated by the high heat which they are subjected, that their main tenance charges have been found to more than negative any operative econom the might otherwise possess. Finally, While the serial application of exhaust and waste gases may eliminate the objec above stated to the former, that which 03.7: tems as to the latter, remains, and apparel-- tus of thischaracter heretofore proposed has generally been open to the further do and maintenance cost.

The-object of my invention is to provide:

a locomotive feed Water heater, which shall sive construction, and ready applicability tolocomotives of any of the present standaz 'd types, in the operation of which the jBCtlOII of complication and high structural coincident To ie stru bore, of q. 1 i A s A ortions 0i and oi ihe perainre o, I degree as will eliect so. sieirtiel economy, Without lnvolrmg laid resisting joints I? dcte lion of the Figure of the boiler, 1 n vencentral omponyi d musings 3%, per: in section, )ortion of a locomotive application r a vertical .lcn cation through the same; 3, a vertical ltl1S-?I8 section, on scale, on 319 line 3, 3, of i f and and 5, a'nsverse sectir on further enlarged scale, on lines i, at, and 5, respectively,

M invention herein exenipiilicd as applied in locomotive boiler, 4i, which is of the usual construction, and is provided, at its forward end, with smoke box, i, which is so. t =e ordiner cylinder sadaiit of tubes, 67, so at the rear end of 'hrongli the tubes, in the usual 7-0 the smoke hora, 4, from which a the atmosphere The usual deflecting i extends (across the flue sheet and the plate, 3, which nc surrounds in xtends forwardly I netting or oeing con ectcd to its front si and ate ,ding across the smoke iiox.

In the practice of my invention, referring descriptii'ely to the specific embodiment thereof which is herein illustrated, I provide :1 heater casing, i, which is ioceted on the exterior e" the boiler and may be most conveniently disses-ed, as shown, in
